Is attached to the tray 11.

  Also with the tray partition 80 according to the third embodiment, the top plate 83 disposed on the top surface unites with the vertical partition plate 81 and the horizontal partition plate 82 to form a stable support surface 89 with a large support area. Since the load from the upper tray 11 can be firmly supported, the same effects as the tray partitions 10 and 70 of the above embodiments can be obtained.

  The present invention is not limited to the above-described embodiments, and various modifications can be made. For example, the product accommodated in the tray does not necessarily need to be a bottle container, and the present invention can be employed to accommodate other various products in a plurality of stages in a visible state. Further, the tray does not necessarily need to be made of cardboard, and may be made of synthetic resin or metal. Further, two or more vertical partition plates may be provided, or three or more horizontal partition plates may be provided to partition the tray receiving recess. In this case, the number of upper half cuts and lower half cuts can be appropriately increased and decreased so that each horizontal partition plate intersects with the vertical partition plate. In addition, the horizontal partition plate does not necessarily have to be attached to the U-shape by placing the top plate or the central top plate on the top surface portion, and the horizontal partition plate provided with the top plate connected to the L shape and serving as a support surface, Only one sheet may be arranged to intersect with the vertical partition plate to form the tray partition body of the present invention. Further, the positioning projection pieces 26a are not limited to one, and a plurality of positioning projection pieces 26a may be provided. The horizontal partition positioning projection pieces 71 are not limited to the second embodiment, and may be provided as one or two pairs.
